    Data science project update

    I finally completed my IBM data science specialization. I completed the 8 first courses of the specialization very fast but the last course took me for ever. I met all kinds of technical issues and had to simplify my final project to the point that I feared I would not get a passing grade. However, this worked and I am really relieved the course is finally over. This does not mean I am over with data science. I want to learn more about this field. The IBM data science specialization was great to have a broad view of different aspects of data science and improve my Python skills. However, I…

    Data science project: machine learning

    This week, I was sick and had to stay home. This was of course bad but this gave me the opportunity both to spend more time with the children (also sick at home) and to work on my data science course. And I finally completed the course 8: Machine learning with Python Course 8: Machine learning with Python I completed the course on December 10th 2019. This was an interesting course. You learn for instance how recommendation systems work on popular websites such as Amazon or Netflix. The part on regression was not totally new. I had already seen these notions in previous courses. However, the parts on classification, clustering…

    Data visualization and machine learning

    I have kept working on my data science specialization course since my last update on the blog. I have been working on topics such as Data visualization and machine learning. The last course are definitely more challenging than the first ones and I learned a lot. Course 7: Data Visualization with Python I completed the 7th course of the specialization: Data Visualization with Python. There were a few things I already knew but I really learned a lot. Some chapters of this course were really cool, like creating a chloropleth map (this is a map where areas are colored to indicate the values of a particular quantity in those areas). Another…

    Data science project: November update

    I have not written on the blog for weeks. However, I have not been lazy. I worked a lot on the data science project. I kept working on the IBM data science track on Coursera. Here is my November update. One of the courses, “Data Analysis with Python”, was very long and it took me more time to complete it than I had needed for the previous courses. Most of the concepts in this course were also completely new to me, compared with the previous course November update: new courses Course 6: Data Analysis with Python I completed this course on 25/10/2019. This was the longest course I took so far and…

    Data Science project: October update

    This is a quick October update on my data science project. I am taking Coursera courses about data science and want to finish the IBM data science track by the end of the year. You can see below my previous posts on the project: My goals for September -> first presentation of the project Book review: Ultralearning (Scott H Young) ->the post is actually about the book Ultralearning but at the end of the article I am showing how the book helped me to define my data science project better Data science project: first weeks -> description of the first courses I took October update: new courses Course 4: Python…

    Data science project: first weeks

    I am still working on my data science project and until now, it is going well. This is not always easy to find time to work on this but fortunately, the first courses of the IBM data science track on Coursera have not been too difficult. The next ones will probably be more challenging however. I could complete the first courses relatively fast. Actually, I think the amount of work needed that is indicated on the courses is not really accurate. Some exercises are supposed to take one hour to complete, but actually, it takes rather ten to fifteen minutes, even if you are not familiar with the subject. Data…

    My goals for September

    Summer is coming to an end and September will be busy. My son is starting nursery school and my daughter has just resumed school. I have also some doctor appointments for the children. And I have some further projects too. This post may contain affiliate links. See the Disclosures page for more information. My data science project I have been interested in learning more about data science for some time now and I finally decided to start working on that. I enrolled to some data science courses on Coursera. I started with the IBM data science course „What is data science?“ which was still pretty easy.  Then, I attempted the…
